According to the absorption of moisture, the tile is divided into eight groups: the first group (absorbs about 3 %moisture) is the most moisture resistant, after it there is a second group (about 6 %), the third group (about 10 %), and t.D. The tiles of the first first groups can be used outside the room, t.to. She will not burst in the cold.
